Fuel pump LBZ

Hey everyone. I know this post has been talked about before but I have read everyone’s reviews that’s are several years old compared to today’s date. With that being said, what is today’s best investment for a lift fuel pump?Manufacturer and GPH size? I have a 06 LBZ that has a edge chip but other then that is stock. I am towing a travel trailer this coming spring for the first time and I am looking to protect my CP3 and longevity of my rig. I love my truck and want it to last a lifetime. Thank you for your input, advice and help.

Kennedy............... high volume, low pressure, centrifugal, silent, long life, no leaks, simple install with no return line required.

Thank you Shop Specialties. I will look in to Kennedy. I have herd some chatter about those but never really any hard core reviews. Even YouTube does not have to many reviews on it. I appreciate the input I am conflicted between the Fass and AirDog. So it is nice to get a third contender thrown into the mix. Thanks.

You won't come close to burning 10gph, towing whatever up Mt. NotToday's slopes, why go for 100gph pump?

The Kennedy is a good pump and the install is elegant. I got the FASS 95 because I liked the idea of "polishing" the fuel by recirculating it through the two filters.

I also like the fact that it is self priming. Makes changing filters easier and no pre-filling required.

Ive only had it about 4 years but it has worked flawlessly.

I wouldn't hesitate to run any of the big names (Airdog, FASS, Kennedy, BD, Aeromotive, etc), they are all reliable and work well. One thing I like about the FASS and Airdog is the "polishing", recirculating the fuel through the filters multiple times appeals to me. Does it make a difference? I can't prove it one way or the other, but it gives me a warm fuzzy, which counts for something.

With some stuff.

Thank you for the input HWI. That is something I like as well when it comes to "polishing" the fuel. There are so many reviews and different inputs out there. It is a good chance of change out of my pocket so I would like to get it right the first time.

Good point 407driver. It looks like to me that the 95gph is no longer sold but rather a 100gph. Must be the new filter setup without the bleeder screw.

Fass still is the 95gph. I just bought one less than a month ago. It's their new titanium signature series with the new style filters.

I did see some sites listed it as 100gph but yet the part numbers were the same as the 95.

Gotcha that makes more sense 19trax95. I did not look at the part numbers. I knew the filets changed but I was also curious why they would move away from a bleeder screw on the water separator. You think it is a new way to buy more filters more often? Thanks
